There are some 100 million other places in the Milky Way galaxy that could support complex life, according to new research by astronomers. They have developed a new computation method to examine data from planets orbiting other stars in the universe.

An historic milestone in artificial intelligence set by Alan Turing -- the father of modern computer science -- has been achieved. The 65 year-old iconic Turing Test was passed for the very first time by supercomputer Eugene Goostman during Turing Test 2014 held at the Royal Society in London on June 7, 2014. 'Eugene', a computer program that simulates a 13-year-old boy, managed to convince 33% of the human judges that it was human.

An alternative to the previous long-held hypothesis that the evolution of the robust faces of our early ancestors resulted largely from the need to chew hard-to-crush foods such as nuts has been presented by researchers. The prehistoric version of a bar fight -- over women, resources and other slug-worthy disagreements -- are what shaped our facial evolution, new research suggests.

New research reveals that rats show signs of 'regret' -- a cognitive behavior once thought to be uniquely and fundamentally human. To measure the cognitive behavior of regret, scientists developed a task that asked rats how long they were willing to wait for certain foods. In this task, the rats are presented with a series of food options but have limited time at each 'restaurant.'

Pathogens entering our body only remain unnoticed for a short period. Within minutes our immune cells detect the invader and trigger an immune response. However, some viruses have developed strategies to avoid detection and elimination by our immune system. Researchers have now been able to show how the herpesviruses achieve this.

Physicists succeeded in the first direct high-precision measurement of a fundamental property of the proton. Results will contribute to a better understanding of the matter/antimatter asymmetry.

Real invisibility cloaks are rather complex and work in certain situations only. The laws of physics prevent an optical invisibility cloak from making objects in air invisible for any directions, colors, and polarizations. If the medium is changed, however, it becomes much easier to hide objects. Physicists have now succeeded in manufacturing with relatively simple means and testing an ideal invisibility cloak for diffusive light-scattering media, such as fog or milk.

Cutting-edge observations with the 1.6-meter telescope at Big Bear Solar Observatory in California have taken research into the structure and activity of the Sun to new levels of understanding. The telescope at Big Bear is the most powerful ground-based instrument dedicated to studying the sun. A group of astronomers has analyzed the highest- resolution solar observations ever made.

A recently rediscovered species of bushcricket uses elastic energy and wing movement to reach high ultrasonic frequencies involving sound levels of about 110dB – comparable to that of a power saw.
